In a prior post I mentioned that I was going to pull the drive train to check out the p/o's alledged rebuild. They said that they couldn't get it to idle. I found alot of blue silicone from the rebuild. Not good. Coupled with the fact that they had installed a hodge podge of FI components I decided to check out this ol' boys work. P&C's looked pretty new (I'll let the machine shop decide that) so I was hoping that everything else was too.
I almost (IMG:style_emoticons/default/stromberg.gif) in my shoes when I pulled the oil pump. This bolt is not only bent but had backed out 3 threads. The one below it was hand tight. looking at the back side you can see the difference in bolt lengths They had to have heard this. |

This was common around Y2K.. A whole batch of cam gears ending up being soft and they'd not hold torque.. It happened to me on one occasion.
Also, the oil pump drive tang is protruding too deep into the drive slot of the cam.. See those two shiny spots where the corners of the oil pump drive have been hitting deep inside the drive slot?? I bet the cam thrust bearings are trashed and the cam is walking fore and aft in the case, that could be why the bolts contacted the oil pump as well. Start taking it apart.
